Einstein ring of dust shells with quantum hair
Sojeong Cheong, Wontae Kim, Mungon Nam
The information about the internal structure of a compact object is classically inaccessible to external observers. In this paper, we investigate how quantum corrections to gravita…

Validity of black hole complementarity in an accelerating Schwarzschild black hole
Wontae Kim, Mungon Nam
Black hole complementarity has been well understood in spherically symmetric black holes. To study its validity for an accelerating Schwarzschild black hole, which has a preferred…

Entanglement entropy of asymptotically flat non-extremal and extremal black holes with an island
Wontae Kim, Mungon Nam
The island rule for the entanglement entropy is applied to an eternal Reissner-Nordström black hole. The key ingredient is that the black hole is assumed to be in thermal equilibri…
